What restaurant in DC area would you recommend for a large party of 30-35 people?

My wife and I are trying to have a semi-formal event for friends and co-workers..What restaurant in DC area would you recommend for a large party of 30-35 people?
I suggest Buca Di Beppo- there's one in DC and one in Gaithersburg. Friendly staff, great family-style food and they have great experience with big groups of people.
If you like modern, moderately priced dining, I'd start with M Street Bar %26amp; Grill, because they've got plenty of space: http://www.capitalhotelswdc.com/MStreetB鈥?/a>



Their sister restaurant is Beacon Bar %26amp; Grill: http://www.capitalhotelswdc.com/BBGWDC_c鈥?/a>

Poste Brasserie has a wonderful private room. Their staff is attentive and fine quality food. Also, try the private room at Vidalia - amazing cuisine, sommelier, and great staff.
I think your best bet for that many people is to rent out a small banquet room at a hotel! You can get it catered, have a bar, and decorate the way you want. If you pick a nice hotel it should make the event formal. There are places in DC like Embassy Suites and the Four Seasons that may be worth checking out!
Cafe Asia. I know there is one in Arlington and I believe there is also one in DC.
